The world is facing challenges to reduce carbon emissions, the complex interplay between socioeconomic dynamics and environmental sustainability is of utmost importance. In the context of the BRICS nations-Brazil, Russia, India, China, and South Africa-this study explores the intricate interactions between institutional entrepreneurship, institutional innovation, poverty reduction, social globalization, urbanization, and social entrepreneurship as well as their combined effects on the carbon footprint over the period of 1990 to 2021. This work examines the multi-dimensional interactions inside this nexus using a thorough analytical strategy that includes the Generalized Method of Moments (GMM), Three-Stage Least Squares (3SLS), and Robust regression approaches. Institutional entrepreneurship and innovation are the main forces behind institutional change and may have an impact on how people behave in terms of the environment. Strategies for reducing poverty frequently involve greater resource usage, which has an impact on carbon footprint. Examining social globalization's impact on carbon footprints is necessary given how it affects consumer habits and economic activity. Rapid urbanization is a dual problem because it spurs both increased energy demand and novel sustainability measures. With its emphasis on community-driven solutions, social entrepreneurship can provide regional solutions to reduce poverty and carbon emissions. The study's findings provide policymakers, practitioners, and researchers with insights into the complex web of socio-economic factors that underlies carbon footprint fluctuations. This research paves the way for informed policy decisions, sustainable business practices, and the pursuit of harmonious development that addresses both economic aspirations and environmental imperatives within the BRICS countries by illuminating the connections between institutional entrepreneurship, innovation, poverty reduction, social globalization, urbanization, social entrepreneurship, and carbon emissions.
